Producing Technology
Hot forging- forging
processabove the recrystallization
temperature.
Hot rolling-
rolling processabove
the recrystallization temperature.
Cold rolling- rolling process of
plastic deformation temperature lower than recovery
temperature.
Annealing- heat
treatment processheating the metal
slowly to a certain temperature sufficienttime,
cooling at a
suitable speed (usually slow cooling and sometimes controlled
cooling).
Acid pickling- metalimmersed in
aqueous solutionswith sulfuric
acid to remove oxides and other films on the metal surface. It is
the pretreatment or intermediate treatment of electroplating,
enamel, rolling and other processes.
Two
popular Grades of titanium plate and
sheet:
Grade
2 Titanium
Gr2- commercially pure titanium used in most
of the chemical processing plants and is cold
formable.
Gr2- ultimate
tensile strength at and above 40,000
psi.
Grade
5 Titanium
Gr5- quenching
and aging treatment
needed, grain structure
of the finished piece is more
homogenous, can
processed to the closest
size of the desired part.
Gr5- ultimate tensile
strength can
be as high
as 120,000
psi.
